Remove most package names for filename-based ATA

[jessetrinity]

Fixes #40123

This greatly reduces the number of different typings packages available to ATA triggered when a .js file is discovered in a VS project or when the file is opened in VS Code.

The rules I used for retaining types are as follows

• The package was in top 20 @types packages on npm.
• The package was in the top 20 downloaded typings for VS users.
• Retain the regex matched packages which we presumably care enough about to go into detail.

20 is a somewhat arbitrary number based on when the number of installs by package levels out at an order of magnitude lower than the most popular package in VS (jquery).

The original issue also mentions adding a status message for typings installed events. VS Code already does this and I have a PR open in the TypeScript-VS repo to add the message there.

Change makes sense to me.

If this issue does have an impact, I expect it will mainly effect newer users and would be reported as "IntelliSense stopped working". I'll keep an eye out for those in insiders and after release (unfortunately newer users are much less likely be insiders too)

After much discussion we have decided that limiting the type names is not the way to go. If we do anything, we should make this behavior configurable separately from typeAcquisition: enable/disable.
